Great danger! Study claims - 4 out of 5 glaciers may disappear by 2100

  Washington, DC. If fossil fuel use continues unabated, more than 80 percent of glaciers could disappear by the end of this century. According to a study, if we talk about numbers, four out of every five glaciers will disappear. Research shows that the world could lose up to 41 percent of its total glacier mass this century. Based on today's efforts to combat climate change, at least 26 percent of the glacier mass will be lost.

An assistant professor at Carnegie Mellon University conducted the research

This study has been done by David Ross, Assistant Professor of Civil and Environmental Engineering at Carnegie Mellon University, USA. He led an international effort to find new estimates of glacier mass loss over the century under different emission scenarios.

Discussions on environmental adaptation and mitigation took place at the United Nations Conference on Climate Change (COP 27) in Egypt, the study said. To support this, projections were aggregated into global temperature change scenarios.

In the best case scenario, 50 percent of the glaciers will disappear

Even in the best-case scenario, during reduced emissions, glacier mass would decrease by 25 percent and about 50 percent of glaciers are projected to disappear. This is when global average temperature increases are limited to 1.5°C above pre-industrial levels.

The disappearance of glaciers has a negative impact
Most of the lost glaciers are small (less than one square kilometer) by that standard, the study said. However, their loss may have adverse effects on local hydrology, tourism, glacier hazards and cultural values.

This study will be a better reference for climate policy makers

Professor David's work has provided a better context for regional glacier modelling. He hoped it would prompt climate policymakers to lower their targets for temperature change below 2.7 degrees Celsius. This promise was made in Glasgow, UK. done in the COP-26 meeting held in Areas with small glaciers, such as central Europe and western Canada and the US, could rise by more than 2 degrees Celsius, the study said.
